This is where every month, you can vote to what map is your favourite and what map is your least favourite. This could help debating on what map to remove & replace. I was thinking another slot being filled with a gold ingot. So, in game I can right click this, and this will open up a menu, where I can choose between Skywars and survival games, and it will bring up a block, representing a map, and at the bottom (imagine a single chest) you drag your choice into a chest. This is a suggested way to do this, but can be changed.
